HARROW-WEIGHT DISTRIIBIITING IlEVICE.

Application filed November 21, 1925. 'SefialNo. 70,643, i

5 This invention'relates broadly to an improved harrow structure, and has more particular (reference to an apparatus or, device tonbe used in association therewith for dis vti'tributing weight. a

' Ordinarily, where a harrow is composed of a plurality of separate tooth carrying frames, it is comparatively difficult to distribute the weight of the operator on all of i the frames. This is due more particularly to the fact that the individual frames travel on different .planes owing to the irregularity 1 of the surfacetraverscd.

lVith the operator or driver usually seated over the central frame, it is obvious how difficult it is to equalize the weight on all frames so that the teeth will be forced sufficiently deep into the surface. s

Briefly, I provide a seat which is located over the center of the central frame of the harrow, and support this seat upon an arch, the lower ends of the arms of which are connected with a pair of individual members for transferring the weight of the operator to the end frames and the central frame in an equalized manner even when the two end frames are travelling on irregular surfaces disposing one in a higher plane than the other. 7

In the accompanying drawings forming a partof this application, and in which like numerals are employed to designate like parts throughout the same 3- Figure 1 is a top plan view'of a harrow invention.

cross bars of the frame. s

Fig. 7 is a perspective view of a two-way connector providing a desirable connection of the pipes with said cross bars.

As previously intimated, the structure embodies three harrow frames 1, 2 and 3, the central frame being designated by the character 2 and the two end frames by the characters 1 and 3. All of these frames are of duplicate construction and are provided with constructed in accordance with the present Fig. 4 is a detail view of the-seat sup-' suitable perforatingteethi Extending across it the (centerof the'top of each frame is a lon g tudinalvcross bar [Fastened'tothe forfwvai'cl ends'pfthe several frames is a suitable draftappliance or hitching device des- Weight distributing and equalizing device-which is represented generally the .ignated generally byt-he reference character 5.

reference character 6, is disposed. over the central portion of the h a'rrow frames and extends transversely of the line of draft. This device comprises an arch '7 better shown in Fig '2l The apenof the archis disposed centrally over the central frame and downwardly diverging arms are provided at theirlower ends with forks 8 which straddle and are pivotally connected to a pair of duplicate pipes 9.

, It will be noted that the inner end por tions of these twopipes are disposed in somewhat overlapping relation as indicated ap-'- proximately by dottedlines in Fig. 1. The opposite ends of both'pipes are'connected to the adjacent cross bars 4. In accomplishing these connections, I employ special twoway connectors 10 such as are shown 1n 7. Each connector'is made up of pairs of spaced ears lland 12 respectively. 'The ears 12 straddle andare 'pivotally connected as at 13 (see Fig. 6) to the bars 1. This allows forward and rearward rocking of the pipes 9. The pipes are connected to the right an- In this way a substantial universal joint is had, which is necessary in the proper oper- Fig.

ture is partially controlled by a pair of pipes 9 connected at their outer ends to the cross connected at their inner ends to the central frame cross bar. There are necessarily two special connectors 10 at theinner endswhile to the intermediate portions of the pipes. The apex of this arch is flattened and the bars 4 on the outer frames and sufficiently" I I horizontal part of a U-shaped member 15,,

rests on and is connected to this .apex.'

The ,operators seat 16 1s adjustably mounted on the horizontal part of this member 15 as more plainly'shown in Fig.1 5;

95 be seen'tha't the weight distributing struc- 1 Referring to this figure it will be seen that I simply provide a clamp including a cross plate 17 and a retaining bolt 18, the bolt passing through the straight parallel por tion of the member 15. The member has the free end portions of its arms extending downwardly at an incline and a strip 19 is fitted between these arms as plainly shown in Fig. 4. This strip is pivotally connected at 20 to the draft appliance and that portion which is confined between the arms of the member 15 is provided with rack teeth manner specified regardless of the relatively 7 different planes that the harrow frames must'occupy in travelling over different elevations of ground. The manner in which this is accomplished is undoubtedly clear and more lengthy description of the structure is deemed unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new is In a structure of the classdescribed, a plurality of individual harrow frames, a draft appliance connected with the forward ends of said frames, a centrally disposed bar extending longitudinally of each frame,two-

Way connectors mounted upon the central I portions ofrsaid bars, a pair of pipes pivotally connected at their opposite ends to said connectors, a vertical arch having the lower ends of its arms pivotally connected with the intermediateportions of said pipes, an extensible connection between the central portion of the arch and said draft appliance, and a seat supported adjacent the central part of said arch.

In testimony whereof I "afiix my signature.
